Harry clammered thruogh the halls as fast as he could. He could hear Ron and Hermione running after him. "Why wouldn't they just help me!", he muttered to himself while swerving around a corner. He ran charging down the stairs and forgetting that there was a missing step he tripped and flew down the stairs into the Hall below. Cursing Harry struggled to get up but herd a snap and knew that his ankle was broken. His mind racing he tried pulling himself into a corner knowing that Peeves or worse Filch would soon be charging to the scene. Footsteps aproached and Harry gave up, he couldn't move it was hopeless. He expected the cry of Filches high piched greasey voice but instead, Hermione came rushing toward his side. "OH Harry! I knew no good would come of this! look at you. Oh no Filch will be here any moment ". Ron taking a more sensible note sugested taking Harry into the empty classroom across the hall first, before deciding anything. They picked up Harry and pulled him into the room. Hermione was fretting muttering things aout Housepoints and failing third year. Then there was a low rumble of some sort. Ron panicked and ran behind a desk followed by Hermione. Seeing as Harry couldn't walk he sat still in a chair in the middle of the classroom. The door creaked and they all gasped to see a dog. Huge shaggy and BLACK.
